CUTTING DEVICE.

Specification of Letters Patent.

Application fileaiui 13, 1916. Serial No. 109,089.

Cutting Devices, of which the following is a specification.

One-object of myinvention is to provide a relatively simple, easily operated device for cutting lengths of fabric from piecesof the same, the invention particularly contemplating an attachment for a fabrlc'measuring machine such as that described and claimed in an application for U. S. Patent filed by Stephen B. Tily John G. Rehfuss and-myself on June 2nd, 1916, Serial Number 101,298;

Another object of my invention is to provide a fabric cutting mechanlsm with novel means for supporting, guiding and transmitting power to a rotary cutter while permitting it to be bodily moved across or through-the material to be severed.

These objects and other advantageous ends I secureas hereinafter set forth; reference being hadto the accompanying drawings, in which Figure 1' s aside elevation of a cutting device embodying my invention;

Fig. 2 is an end elevation of the device" shown in Fig. 1;

Fig. 3' is a' plan of the parts shown in Figs. 1 and2; and

Fig. 4 is a vertical section on an enlarged scale taken on the line k-l, Fig. 3.

In the above drawings 1 represents a plate or bar in which is formed a'longitudinally extending under-out guid'eway for-the reception of a slide 2 of corresponding section on which is'mounted a cutter carriage hereafter described which includes a bearing 3 for the reception Of a shaft 4: extending in a line at right an les tO the line of movement of the slide. rojecting fromsaid bearing is a Vertically extending standard 5- terminating in a substantially vertical bearing 6 designed for the reception of Oneend of a flexible shaft 7 which has fixed to it a bevel gear 8 in mesh with a second beveled gear 9 fixed to'the spindle l adjacent one end thereof. On the opposite end of said spindle is" fixedly mounted a sharp edged rotary or disk cutter 10 which receives its power from the flexible sha'ft 7 through the gears 8 and 9 and the shaft 4.

As shown in Fig. a, the slide 2 has hinged I or pivoted to it a plate 11 extending substantially parallel with its upper surface and normally pressed up by a spring 12.' Its position relatively to the slide may, however, be regulated bymeans of a thumb desired manner, although in the present case we have shown it as delivered by a pair of rolls 20 and 21.

the plate 16 for any suitable and desired distance as determined by the adjustment of;

the screw 13, andjobviously," as this latter 'is backed off, the spring 12 turns on its pivot 22themember 11 and moves the plate 16 upwardly toward the shaft 4:.

After the fabric to be operated on has been fed out overthetable 19, the carriagecom prised by the slide 2, bearings 3 and 6 and with their attached parts, is

standard 5 moved longitudinally of the'plateor bar 1, thus-causing said fabric to be cut as it enters between the downwardly flared advancing end of the elongated plate 16 and the ad- Patentea Apr; as, rare.

11 is extended at one sideof the slide and isthereafter turned 'downwardly'as indicated at 14; having fixed to its lower extremitya handle lowherebythe slide with its associatedf] parts may be moved longitudinally in the groove or guideway of thesupporting structurel. This downwardly extending portion 14: has also fixed to it a horizontally e101. gatedplate 16, longitudinally slotted for the reception of the edge of the cutter 10 and it likewise carries a cutter guard plate "17 vlying in a plane parallelwith that of the 'outf ter. Said guard plate'is turned over the top of the cutter and is also turned over 'atfi oneend as indicated at 17 and 18. The goods or piece of fabricto be out rest upon a supporting plate or table 19 O'Verthe free f edge of which the slide-supporting bar is carried and said piece may be fed in any y vancing end of the guard plate 17. Since t e cutter is preferably rotated at a high speed and is kept in a well sharpened condi tion, there is but little resistance to the carriage as the slide 2 is moved through the guideway, preferablyby force exerted on the handle and a clean straight out is made across the piece of fabric, the severed end of which may then be removed in order to permit of another length of fabric being run out over the'table 19.

. mg the cutter.

own in Fig. 2 the cutter 10 is clamped by means of a nut 23 between a pair of collars 24 and 25 mounted on the shaft 4 so that it may be removed or replaced as desired. 7 i

While in Fig. 2 I have shown the guard plate '17 as removably clamped to the downwardly extended portion of the plate 11, by means of a thumb screw26, it is to be understood that it may be permanently connected to saidelement in any desired manner without departing from my invention.

I claim r 1. The combination of a table for supporting fabric to be out, including a slide having a depending portion; a carriage movable across said table; a rotary cutter on said carriage and operative in the plane of said depending part of the slide; means for driving said cutter; a plate mounted on the depending portion of the slide in position to cooperate with the cutter; and a handle carried'by said plate below the table. 7

he combination of a table for supporting fabric to be cut; a carriage movable across said table; a plate mounted on the carriage and supported with its top surface in the plane of the table top; a rotary cutter also on the carriage in position to cooperate with the plate; with means for driv- 3. The combination of a table for supporting fabric to be out; a carriage movable across said table; a slotted plate mounted on the carriage and carried thereby with its top surface in the plane of the table surface; a rotary cutter extending into the slot of the plate and also mounted on the carriage; with means for driving said cutter.

4. The combination of a table for supportbe cut; a carriage movable across sa1d table; a plate mounted on the carriage with its top surface flush with that of the table; a rotary cutter also on the carriage in position to cooperate with the plate, the latter being supported from the carriage through a portion in the plane of the cutter; with means for driving-the cutter.

5. The combination of a table for support- Copies of this patent may be obtained for 7 means for ing fabric to be cut, having an elongated slot; a carriage movable across said table and having a depending portion; a plate mounted on said depending portion and operative in the slot of the table with its top flush with the table top; a rotary cutter also on the carriage in position to cooperate with the plate; and means for driving the cutter.

6. The combination of a supporting structure having a guideway; a carriage having a slide movable in said guideway; a rotary cutter supported 011 the carriage; a plate adjustably connected to the slide in position to cooperate with thecutter; a spring for moving the plate in one direction when it is adjusted on the carriage; and means for driving the cutter.

7 The combination of a supporting structure having a guideway; a slide movable therein; a plate pivotally mounted on said slide; a bearing also carried on the slide; a shaft mounted in the bearing; a rotary cutter on the shaft extending adjacent the plate; means for driving said cutter; and turning the plate on its pivotal support to vary its relation to the cutter.

8. The combination of a supporting plate having a guideway; a slide movable in the guideway; a lateral projection from the slide having a downward extension; a plate carried by said extension and provided with an operating handle; a bearing on the slide; a shaft in the bearing; means for turning the shaft; with a rotary cutter fixed to the shaft and extending into a slot in said plate.

9. The combination porting a piece of fabric; a carriage including a body portion movable adjacent said structure; a plate pivoted to said body portion and extending substantially parallel with the top surface thereof; a spring normally tending to move the plate relatively to the body portion; a set screw for regulating the position of the plate; a cutter carried by the body portion and cooperating with the plate; and means for driving the cutter.

10. The combination of a structure for supporting a body of fabric; a carriage movable across the same and including two bear ings substantially at right angles to each other; a plate carried by said carriage with its top face flush with that of said supporting structure; shafts operative in said bearings; gears connecting said shafts; a flexible shaft operatively connected to one of the shafts; a rotary cutter fixed to the other shaft in position to cooperate with the plate; and a handle projecting from said plate below the table for moving said carria e.
